Patented Feb. 2, 1944 HANDLE Gerald V. Jakeway, G signor to Keeler Brass Miclu, a corporation rand Rapids, Mich, as-

Company, Grand Rapids, 1' Michigan Application June 12, 1941, Serial No. 397,678 14 Claims. (Cl. 292-347) This invention relates to improvements in handle.

The main objects of this invention are:

First, to provide an improved handle or the like for automobile doors, remote controls, drawer pulls, and the like which may be produced in highly ornamental designs to match the desired finishes or plans of the structure to which it is applied.

Second, to provide a structure having these advantages which is simple and economical in its parts and in the assembly thereof and very strong and durable.

Third, to provide an improved method of manufacturing handles, remote controls, and the like which may be practiced for rapid production and with great economy.

Objects relating to details and economies of the invention will appear from the degcription to follow. The invention is defined in the claims.

Preferred embodiments of the invention are illustrated in the accompanying drawing, in which:

Fig. 1 is a side elevation partially broken away and in longitudinal section of a door handle embody n my invention.

Fig. 2 is an enlarged transverse section on line 2-2 of Fig. 1.

Fig. 3 is an enlarged transverse section on line 33 of Fig. 1.

Fig. 4 is a fragmentary view illustrating steps of the method employed in assembling and fabrieating of articles embodying my invention, the parts being shown in full lines in their preformed shape and in assembled relation prior to the heat forming step and in completely assembled relation by dotted lines.

Fig. 5 is a cross sectional view similar to that of Fig. 3 of a modified form or embodiment of my invention.

In the embodiment of my invention illustrated in the accompanying drawing, I designates generally a handle such as is commonly employed for operating automobile doors, remote controls, and the like, the spindle or chill being indicated at 2. I have not attempted to illustrate other types of handles and remote controls for which my invention is well adapted.

In the embodiment illustrated, the handle comprises an elongated metal core 3 of rectangular section and suitable length. Th spindle socket l is attached to this core, the details of attachment not being illustrated.

I provide an inner casing member i and an outer casing member 8, the casing 8 having an internal channel I receiving and fitting the inner portion of the core, the outer member having an internal channel I receiving and fitting the outer portion of the core.

Figs. 2 and 3 are transverse sections of different parts of the handle and their diflference in shape and transverse dimensions of the parts being due to the shape of the particular handle.

The inner casing member 5 is provided with rearwardly projecting longitudinal ribs 9 adjacent the sides thereof, providing longitudinal grooves Ill, The outer casing member is of such channel section that its sides H embrace the sides I2 of the inner member.

The edge portions I3 of the outer casing member are folded around the ribs 9 and into the grooves ill in edge abutting relation to the bottoms of the grooves, thus clampingly retaining the casing members upon the core member.

In the preferred embodiment, both casing members are formed of thermoplastic material and are premolded, the sides ll being in its premolded condition as shown in Fig. 4-that is, they are straight.

In assembling, the parts are arranged in nested relation, as shownin Fig. 4, and placed in the die member II and it will be observed that the sides of the outer casing member project substantially beyond the ribs 9 of the inner casing member. The forming die I 5 is provided with suitable heating means indicated at it and the die members are gradually closed as the edge portions of the sides of the premolded member 6 become heated. Preliminary heating and plasticizing might be resorted tothat is, heating be- ;fore placing in the mold but that involves some ,difliculties in handling. I have illustrated electric heating means but gas or steam or other heating means might be employed. Where the die is heated, its closing is suitably timed with the heating of the portions to be formed.

It will be noted that the die has curved recesses l1 which contact the heated edges of the outer casing member and as the die is closed they are curled inwardly around the ribs 9 and into the grooves l0.

' In this preferred embodiment, the edges of the outer casing member are brought into abutting supporting and retaining relation to th bottoms of the grooves Hi. If desired, some fusing action may result from the heating of these abutting portions or a solvent may be applied to eilect a fused autogenous connection between these mengaging parts. However, the structure is very desirable without that feature.

The edges or the outer casing member are entirely concealed so that a unitary appearance results and in fact the completed structure is a unitary structure, with the outer casing member suitably conformed to the desired design or ornamentation and the inner casing member has a longitudinal rounded center portion 88 convenient for grasping.

This assembling operation may be quite rapidly performed. The resulting structureds strong and rigid and attractive in appearance. A great variety of colors and designs are possible.

In the modification shown in Fig. 5, the inner casing member I! is for ed of metal, otherwise the parts are very similar to those described.

Embodiments of the invention which incorporate the principles of the invention in a highly desirable manner have been illustrated and described. It should be understood that the foregoing terminology is used descriptively rather than in a limiting sense, and with full intention to include equivalents of the features shown and described, within the scope of the following claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
